sass-Conn FASTENER.

Application filed June 2,

My n-csent invention refers to certain new and useful improvei'ncnts in sash cord fasteners. The primary object of the invention is to enable the cords or hanging members to be attached to window sash frames much more readily than has hitherto been possible, and especially to enable said cords to be replaced or readjusted with great facility and accuracy, without any necessity for kuotting; the end of the cord, and without removing the sash from the frame in repair lug or rcattaichinp; the cord, a process which is always attended with ,sgreat discomfort to the occupants of a room, especially in cold weather; and also the lirst hanging of the sash is rendered easiand quicker.

The invention, with these desirable ohjects and many others in view, may he said to consist essentially in a small metallic plate to which the end o'lt'the cord removably attached, which plate is quickly and easily insertable into or removable :t'rom a small pocket on the inner face of the window sash without removing the sash from its frame and thus exposing the interior of a room to chilling drafts or other lll'lifllVOl'ttlJlQ influences.

And the invention may also be said to consist essentially in the construction, come biuation and arrangement of parts, substantially as will be hereinafter described and claimed.

In the annexed drawing illustrating my invention 'Figur'e l is an inner :tront face View of one of the stiles oil? a window sash, ith its supportin5; cord, and my improved fastener for the cord applied thereto, certain parts being sectioned to bring); out the detail construction and arrangement more clearly.

left hand stile. The outer edge 22 ot' this stile, which is next to the window li'ran'ic when the sash is in position, is provided with the customary groove 5 adapted to accmnmodate the sash cord 6, the top end o'lf which runs over a pulley in the window frame and carries the sash weight, (not shown) while the lower end runs for a suit-- able distance from the top of the sash, say a few inches down through the groove 5, mil it it reaches a horizontal connecting or deflecting groove or passage 7 which coimimnica with a pocket or recess 8 in the stile it, which pocket 8 has an opening on the inner :lface l oi stile A and is titted with a pivoted or hinged cover 9, said pocket 8 hemp; adapted to receive and hold the fastening device which thus fastens the cord (3 to the sash. The inner edge of stile A is formed with a head (i; opposite to groove 5, which head acts as the usual should against which the pane oi glass 3 is secured by brads and putty l or by any other means.

The cord fastener consists of a small reotangular metallic plate it), having; one or more openings or perforations 11, and at one end a right-angled flange or lug 12. Plate 10 is adapted to be seated. in the bottom of recess 8, wherein it lies flat or more or less inclined, one end being; lii'ted away from the bottom of the recess 8 by the lee 12, or it the cord 6 is larger than the width of lug 12, the cord. itself will lift the end ol' plate 10 and the lug); 12 away from the bottom of recess 8, and it is so shown in Figure 3; but in many cases the cord will be smaller than the width o't lug 12 and will pass through passage 7 from groove 5 and lie under the plate 10, the cord beinnj turned at an angle to permit this. The cord will also be against the inner face oil lug; l2, whoz-ic edge as si t may or may not touch the bottom o'l' recess R, deliielujiing on the illicitness of the cord.

The cord also in its altiuchuicnt to plate 10, not only turns at an angle to pass under it, but it is also passed through the round hole or opening 11 in plate 10, and then. allowed to lie close against plate .10. The cord is clamped tightly in this position against plate 10 by means of a, clamping, plate 14, having at its ends the angular or lightning-led flanges 15, which are preferably toothed or serrated at 16. Vl llQll the clamp lei. is in position binding over cord (l as shown in Figures "l and i t will he securl-id III) t; Ci

lou

to plate 10 by screws 17 entering screw holes in clamp 14 and coincident screw holes in plate 10, see Figure .5, and thus the clamp 14 clamps very tightly against cord 6, and its toothed flanges bite into the cord (3, so that a gripping of the cord takes place which cannot be released no matter how hard a pull is applied to cord 6, and it is therefore impossible to detach the cord from the sash by hard and prolonged usage, and it will do its work effectually until worn out or broken and rendered useless, when the end can easily be taken out by removing clamp 14, and then inserting the end of a new cord, and re-securing the clamp over it.

It will be seen that in inserting this cord, either a fresh one or a repaired one, it can be pushed down through the groove 5 from. the top of the sash, without taking the sash out of the window, and when the lower stiff end of cord 6 strikes the cross groove 7 it will be deflected sidewise into the pocket 8, where it can readily be taken hold of and the fastener device clamped thereon, so that when the cord is pulled back from above, the fastener device will lodge itself firmly in the pocket 8, thus connecting the cord tightly to the sash; and the repeated movements of the sash up and down in opening and closing the window will only serve to more and more tightly anchor the fastener in the pocket 8. And it is to be particularly noted that access to the pocket 8 is had on the inner face 1 of sash stile A by simply switching away the cover 9 that is held by screws 13, 13, or otherwise. Thus in con necting the cord to its fastener I do not disturb the sash itself. It remains as usual in its frame, and the window is kept shut. The repair or readjustment is made very quickly, and is positive and sure. The device is simple and economical and thereby many useful results are made possible.

Many changes in the details of parts and their relative sizes and positions may he made without departing from the invention as covered by the ensuing claim. ()hviously a single window has two sashes and hence four cords are necessary, or two for each sash; but each cord may make IIH of my improved fasteners with equal facility. And indeed the fastener may he applied to weighted cords employed with other kinds of windows, or doors, or other similar fillllt" tures without varying from the invention. It is important to note that the cord is without knots or clasps for holding it, as none are needed when my improved fastener is used.

Having thus described my invention what I claim as new and desire to claim, is:

In a sash cord fastener, the combination with a window sash having the stile provided with a groove receiving the cord and a pocket in communication with said groove, of a fastener adapted to be seated in said pocket and consisting in a flat plate perforated near one end through the perforation of which the cordis passed, said plate having an angular lug adjoining the perforation, and a clamp for clamping the cord between itself and the plate so that the cord may he held tightly against the plate, said clamp having angular toothed flanges that engage the cord, and screws entering holes in the clamp and plate for uniting the clamp and plate tightly together.

In testimony whereof I hereunto allix my signature.
